The external I/F 503 is an interface with an external device. The external device may be a recording medium 503a. Thus, the computer 500 can execute reads and/or writes on the recording medium 503a via the external I/F 503. The recording medium 503a may be a flexible disk, a CD, a DVD, an SD memory card, or a USB memory.

The ROM 505 is an example of a non-volatile semiconductor memory (a storage device) that can hold programs and data even when the power is turned off. The ROM 505 stores a BIOS (Basic Input/Output System) that is executed when activating the computer 500, and programs and data for OS (Operation System) setting and network setting. The RAM 504 is an example of a volatile semiconductor memory (a storage device) to store programs and data temporarily.

The CPU 506 is a processor that implements control and functions of the computer 500 as a whole, by reading the programs and data into the RAM 504 from the storage device such as the ROM 505 and the HDD 508, and executing processes.

By the hardware configuration of the computer 500, for example, as illustrated in FIG. 3, the information accumulation device 10 and the relay server 19 can implement various processes as will be described later.

<<Terminal>>

Also, in the cooperative processing systems 1 and 1a in the present embodiment, by having the NFC devices 15 to 18 obtain the device information, a user can save the trouble of inputting the device information into the smart phone 11.

<<File Output Process>>

In the following, a file output process in the cooperative processing system 1 will be described as an example. A file output process in the cooperative processing system 1a is the same except for a step to obtain the device information.

FIG. 11 is a sequence chart of an example of a file output process in the cooperative processing system 1 according to the present embodiment. The sequence chart in FIG. 11 illustrates a process to have a file output on the projector 12A, upon a request from the smart phone 11 connected with the network N1 such as a telephone communication channel.

At Step S1, the device information obtainment unit 41 of the smart phone 11 obtains the device information illustrated in FIG. 8 from the NFC device 15A. Then, the smart phone 11 executes a device connection process as will be described later.

At Step S2, the file output request unit 42 of the smart phone 11 transmits a request for outputting a file on the projector 12A to the relay server 19. The request for outputting the file transmitted at Step S2 is configured, for example, as illustrated in FIG. 12.

FIG. 12 is a configuration diagram of an example of a request for outputting a file. The request for outputting the file in FIG. 12 includes an information accumulation device ID, authentication information of the information accumulation device, device connection information, and a request command. The information accumulation device ID is an ID to identify the information accumulation device 10, and is used by the relay server 19 to manage the request. The authentication information of an information accumulation device is authentication information of the smart phone 11 to access the information accumulation device 10, and is used by the information accumulation device 10 to inhibit an invalid access.

The device connection information includes an IP address and a host name to establish a network connection with an electronic device such as the projector 12A, which is obtained from the NFC device 15A. The request command is a command to execute the IF provided by an electronic device such as the projector 12A. For example, the request command may be an HTTP request to execute the IF of the Web API.

At Step S3, the information accumulation device 10 transmits a request for obtaining a request to the relay server 19. At Step S4, the information accumulation device 10 obtains the request for outputting the file in FIG. 12 from the relay server 19. At Step S5, based on the obtained request for outputting the file in FIG. 12, the information accumulation device 10 has the projector 12A, specified by the device connection information, execute outputting the file depending on the request command. Note that the file output process executed by the information accumulation device 10 and the projector 12A at Step S5 will be described in detail later.

At Step S6, the information accumulation device 10 returns an output result obtained from the projector 12A to the relay server 19 as a response to the request at Step S4. At Step S7, the relay server 19 returns the output result obtained from the information accumulation device 10 to the smart phone 11 as a response to the request at Step S2.

The device connection process at Step S1 is executed, for example, as follows. For example, a user holding the smart phone 11 enters the conference room A, and activates an application to execute a file output process. The application to execute the file output process activated on the smart phone 11 executes a device connection process, for example, as illustrated in FIG. 13.

FIG. 13 is a flowchart of an example of the device connection process. The device information obtainment unit 41 of the smart phone 11 obtains at Step S11 the device information of all electronic devices installed in the conference room A by requesting the device information to the NFC device 15A.

At Step S12, by using the obtained device information of the electronic devices, the screen control unit 44 of the smart phone 11 transmits a connection confirmation request to the relay server 19. If the connection is confirmed with the electronic device, at Step S14, the screen control unit 44 displays buttons 1001 on a file display screen as in FIG. 14 in a state where a button can be selected to make a request for outputting a file on the electronic device.

If the connection is not confirmed with the electronic device, the screen control unit 44 displays the buttons 1001 on the file display screen as in FIG. 15 in a state where a button cannot be selected to make a request for outputting a file on the electronic device.

FIG. 14 is an image view of an example of the file display screen in a state where a button can be selected to make a request for outputting a file on the electronic device. FIG. 15 is an image view of an example of the file display screen in a state where a button cannot be selected to make a request for outputting a file on an electronic device.

For example, the screen control unit 44 of the smart phone 11 displays the file display screen as in FIG. 15 until the connection is confirmed with the electronic device by the connection confirmation request at Step S12. Having confirmed the connection with the electronic device, the screen control unit 44 displays the file display screen in FIG. 14 in which the buttons 1001 to make a request for outputting a file on the electronic device are updated from the non-selectable state to the selectable state.

A user can make a request for outputting a file on the file display screen in FIG. 14, by pressing a "project by projection" button included in the buttons 1001 to make a request for outputting a file on the electronic device. If the "project by projection" button is pressed, the file output request unit 42 of the smart phone 11 has the projector 12A output, for example, a file displayed on the right side of the file display screen in FIG. 14.

The file output process executed by the information accumulation device 10 and the projector 12A at Step S5 is executed, for example, as illustrated in FIG. 16. FIG. 16 is a sequence chart of an example of a file output process executed by the information accumulation device 10 and the projector 12A.

The relay client 30 of the information accumulation device 10 obtains a request for outputting a file from the relay server 19. At Step S21, the relay client 30 transfers the obtained request for outputting the file to the Web API 25. At Step S22, the Web API 25 transfers the request for outputting the file to the Web control 32. At Step S23, the Web control 32 transfers the request for outputting the file to the external device service 29.

At Step S24, based on the transferred request for outputting the file, the external device service 29 makes a request for obtaining the file to the document management 28. Here, the file is assumed to be stored in the shared folder 27 in the information accumulation device 10. The document management 28 converts the file requested for obtaining the file from the external device service 29 into a format that can be output by the projector 12A, and returns the converted file to the external device service 29.

Note that the format conversion process may be executed after the request has been made for obtaining the file, or at a timing when a user saves the file in the shared folder 27. At Step S26, based on the request for outputting the file transferred at Step S23, the external device service 29 has the projector 12A output the file in response to the request command.

At Step S27, the external device service 29 receives an output result from the projector 12A. At Step S28, the external device service 29 returns the output result obtained from the projector 12A to the Web control 32 as a response to the request at Step S23. At Step S29, the Web control 32 returns the output result obtained from the external device service 29 to the Web API 25 as a response to the request at Step S22. At Step S30, the Web API 25 returns the output result obtained from the Web control 32 to the relay client 30 as a response to the request at Step S21.

In this way, in the cooperative processing system 1 in the present embodiment, if a user enters the conference room A while holding the smart phone 11 that cannot be connected with the network N3 having an electronic device such as the projector 12A connected, the user can control the electronic device from the smart phone 11.

If the file obtainment succeeds at Step S72, the information accumulation device 10 receives the file as a file obtainment result of the request for obtaining the file, back from the projector 12A. If the file obtainment fails, the information accumulation device 10 receives an error from the projector 12A.

At Step S73, the information accumulation device 10 returns the file obtainment result obtained from the projector 12A to the relay server 19 as a response to the request at Step S71. Also, at Step S74, the relay server 19 returns the file obtainment result obtained from the information accumulation device 10 to the smart phone 11B as a response to the request at Step S69.

Having obtained the file obtainment result from the relay server 19, the screen control unit 44 of the smart phone 11B displays the obtained file on the file obtainment screen as illustrated in FIG. 22. Note that if Step S72 is a step that takes a long time, Step S74 may not be executed as a response to the request at Step S69, but executed as a response to a request for obtaining the file obtainment result from the smart phone 11B.

In this way, in the cooperative processing system 1 in the present embodiment, a user(s) can control an electronic device from the smart phones 11A and 11B that cannot be connected with the network N3 having an electronic device such as the projector 12A connected.

For example, the cooperative processing system 1 in the present embodiment can have the projector 12A output (project) a file, have the IWB 13A output (display) a file, and have the MFP 14A output (print) a file, from the smart phone 11A.

Also, in the cooperative processing system 1 in the present embodiment, the smart phone 11B, which is different from the smart phone 11A, can obtain a file being output by the projector 12A, and can obtain a file being output by the IWB 13A. Also, the smart phone 11B can obtain a file scanned by the MFP 14A.

<<Log Saving>>

In the file output process illustrated in FIG. 11, the cooperative processing system 1 in the present embodiment may automatically save a log in the information accumulation device 10. If saving the log in the information accumulation device 10, Step S5 in FIG. 11 is processed as illustrated in FIG. 25. FIG. 25 is a sequence chart of another example of a file output process executed by the information accumulation device 10 and the projector 12.

The sequence chart in FIG. 25 has Steps S108 to S109 in addition to the steps in the sequence chart in FIG. 16. Having received an output result from the projector 12A at Step S107, at Step S108, the external device service 29 makes a request for log saving to the log management 31.

The log management 31 saves a log that includes user information of a user operating the smart phone 11, a request command included in a request for outputting a file, device connection information, date and time, an output result, and the like.

At Step S109, the log management 31 returns a result of the log saving to the external device service 29. In this way, the cooperative processing system 1 in the present embodiment has the information accumulation device 10 automatically save the log of a file output process.

In the file obtainment process illustrated in FIG. 17, the cooperative processing system 1 in the present embodiment may automatically save the log in the information accumulation device 10. If saving the log in the information accumulation device 10, Step S45 in FIG. 17 is processed as illustrated in FIG. 26. FIG. 26 is a sequence chart of another example of a file obtainment process executed by the information accumulation device 10 and the projector 12.

The sequence chart in FIG. 26 has Steps S127 to S128 in addition to the steps in the sequence chart in FIG. 23. Having executed a file save process at Step S126, at Step S127, the external device service 29 makes a request for log saving to the log management 31.

The log management 31 saves a log that includes user information of a user operating the smart phone 11, a request command included in a request for outputting a file, device connection information, date and time, an output result, and the like. At Step S128, the log management 31 returns a result of the log saving to the external device service 29. In this way, the cooperative processing system 1 in the present embodiment has the information accumulation device 10 automatically save the log of a file output process.

Note that the log saved by the log management 31 may be provided for a user by using the Web UI 24, or may be provided for a user by using the shared folder 27. In this way, if an electronic device is controlled from the smart phone 11, the cooperative processing system 1 in the present embodiment can save the log, and hence, monitoring becomes easier for an administrator.

<<Restriction on File Obtainment Process>>

If the cooperative processing system 1 in the present embodiment has the IWB 13A display a file upon a request from the smart phone 11A, and the smart phone 11B can obtain the file unconditionally, it could be a security problem.

Thereupon, if having an electronic device display a file of which the access right is given only to the user of the smart phone 11A, the cooperative processing system 1 in the present embodiment automatically inhibits other users from obtaining the file.

For example, at Step S24 in FIG. 16, the external device service 29 has the document management 28 confirm the access right of a file relating to a request for obtaining the file. If the access right is given only to the user who has made the request for outputting the file, the external device service 29 transmits, at Step S26, the request for outputting the file, and information about inhibiting the other users from obtaining the file, to the projector 12A. Having received the information about inhibiting the other users from obtaining the file, the projector 12A does not provide the file when receiving a request for obtaining the file by the other user, but returns an error. Note that if the user of the smart phone 11A transmits a parameter to explicitly permit another user to obtain the file, the projector 12A provides the file without returning an error.

In this way, if having an electronic device such as the IWB 13A display a file that should not be obtained by the other users, the cooperative processing system 1 in the present embodiment can inhibit the other users from obtaining the file.

<<Displaying User Having Executed File Obtainment>>

In the cooperative processing system 1 in the present embodiment, a file displayed on, for example, the IWB 13A upon a request by a user can be obtained from the IWB 13A by another user. However, the user having the IWB 13A display the file does not know who has obtained the file. Thereupon, the cooperative processing system 1 in the present embodiment has the IWB 13A display information about a user who has obtained a file so that the user who has obtained the file can be confirmed.

For example, at Step S54 in FIG. 23, the external device service 29 adds user information into a request for obtaining a file. The projector 12A executes a process to display the user information included in the file obtainment request.

In this way, in the cooperative processing system 1 in the present embodiment, a user can confirm that another user has obtained a file as intended, confirm that an unintended user does not obtain a file, and confirm who has obtained the file.

<<Saving Additional Information>>

In the cooperative processing system 1 in the present embodiment, depending on an electronic device outputting a file, various information may be added by hand-writing or the like. A user may want to save the information added in this way in the information accumulation device 10. Thereupon, after having an electronic device output a file, the cooperative processing system 1 in the present embodiment automatically saves the output contents having the additional information added at predetermined intervals.

For example, after having made a request for outputting a file at Step S26 in FIG. 16, the external device service 29 can obtain the output contents having the additional information added from the projector 12A, by making a request for obtaining a file on the projector 12A at predetermined intervals. For example, in a conference, output contents having additional information added is a snapshot of discussion contents, and hence, can be used for the minutes.

<Summary>
